Question

distinguish between cerebrum and spinal cord

Answer 1

Cerebrum: which is just Latin for "brain" -- is the newest and largest part of the brain as a whole.  It is here that things like perception, imagination, thought, judgment, and decision occur.

The spinal cord is a long, thin, white, soft and tubular bundle of nervous tissue, running through the backbone and support cells that extends from the brain. The main difference is that in the cerebrum, the surface is composed of grey matter (where there is a high concentration of neuronal cell bodies) over white matter (mostly nerve fibers and supporting structures), and in the spinal cord, white matter covers the grey matter.
